Generalized free wreath products and their operator algebras
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract We develop a new approach on free wreath products, generalizing the constructions of Bichon and of Fima‐Pittau. We show stability properties for certain approximation properties such as exactness, Haagerup property, hyperlinearity, and K‐amenability. We study qualitative properties of the associated von Neumann algebra: factoriality, primeness,

Stability and uniqueness of bounded weak solutions to triangular degenerate cross‐diffusion systems
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract The continuous dependence on the initial data and consequently the uniqueness of bounded weak solutions to a class of triangular reaction‐cross‐diffusion equations is shown. The class includes two‐species doubly degenerate equations for nutrient taxis models describing the response of bacteria to nutrient conditions.

Positive and bounded nonstandard finite difference scheme for the Hodgkin–Huxley equations [PDF]
, 2018 In this work we consider the Hodgkin Huxley model in the form of a coupled system of one singularly perturbed partial differential equation and three ordinary differential equations.

Advancements And Applications Of Nonstandard Finite Difference Methods
, 2015 A class of dynamically consistent numerical methods are analyzed for general n-dimensional productive-destructive systems (PDS). Using this analysis, a methodology for constructing positive and elementary stable nonstandard numerical methods is ...

Numerical Solution and Analysis for Acute and Chronic Hepatitis B
International Journal of Analysis and Applications, 2018 In this article, we present the transmission dynamic of the acute and chronic hepatitis B epidemic problem to control the spread of hepatitis B in a community. In order to do this, first we present sensitivity analysis of the basic reproduction number R0.

A nonstandard finite difference scheme for a Fisher PDE having nonlinear diffusion
, 2003 A number of important phenomena in ecology can be modeled by one-dimensional, nonlinear reaction-diffusion PDEs. This paper considers a modified Fisher PDE for which the diffusion term is nonlinear.
